[Hm. This didn't crosspost when I posted it to cctech, so here it is again,
addressed to cctalk. Sorry if you get this twice.]
Well, I've finally moved from acquire mode into play mode. First, I'm trying
to get this uPDP-11/23+ running. I've got so far as a BA23 with PSU, fans,
backplane, front panel, RD52, and RX50 -- that seems to power up without any
problems. Now I'm going to put the boards in, and I need help. Here's what I
plan on doing:
Backplane is H9278-A: slots 1-3 Q22/CD, slots 4-8 Q22/Q22.
AAAAAAAAAA BBBBBBBBBB CCCCCCCCCC DDDDDDDDDD
1 M8189----(KDF11-BF)------------------------
2 M9047----------------
3 M9047----------------
4 M8067-LB-(MSV11-P)-------------------------
5 M7957----(DZV11-M)-------------------------
6 M8639-YA-(RQDX1)---------------------------
7 M9047---------------- M9047----------------
8 M9047---------------- M9047----------------
The memory is in slot 4 because its grant continuity jumpers (W1 and W2) are
soldered in, which (according to the MSV11-P user's guide) tells me it
expects a Q22/Q22 slot instead of a Q22/CD slot.
Question 1: does the above look OK, or have I got something wrong?
Question 2: Should I try it first with just the CPU and memory in, just to
get a boot prompt on the console?
I'm subscribed to both lists, so feel free to reply to either one.
